step 2: do the math

if you have a low processor and a mid ram and low video card: low+mid+low= low settings

low+low+high:low
low+mid+[high,insane]:mid-low
mid+mid+low: mid-low settings
mid+mid+mid: mid settings
high+mid+mid: mid settings
high+high+mid: mid-high settings
high+high+high: high settings
insane+high+high: high settings
insane+insane+insane: give me your computer

if you have something lower than everything posted above forget about this game and throw your piece of sh1t in the garbage
